Compact radar device e.g. for detecting objects embedded in wall has housing divided by printed circuit board into hollow cavity for antenna device and shielded chamber for electrical circuits

摘要

The radar device has a transmission and reception antenna device provided by at least one hollow cavity (3) containing a radiation element (10) and a shielded chamber (2) for housing electrical circuits (4), mounted on a printed circuit board (5), acting as the shielding partition dividing the housing (1) of the radar device into the hollow cavity and the shielded chamber.
